Embodiment 1
[0048] like figure 1 As shown, a protein-protein interaction site prediction method based on a deep graph convolutional network, the method includes the following steps:
[0049] S1: According to the sequence and structural information of the protein, extract the node feature matrix and the adjacency matrix containing edge information to form a protein graph representation together;
[0050]S2: Use deep graph convolution based on initial residual and identity mapping to capture the characteristics of high-order spatially adjacent amino acids; and input a multi-layer perceptron at the output of the last graph convolution layer of deep graph convolution, Realize the final prediction of the protein interaction probability of each amino acid, and complete the construction of a deep graph convolutional neural network;
[0051] S3: extract the training data through step S1 to obtain the protein graph representation, and use the five-fold cross-validation method to train the deep gr...
